# AI News Digest - 2026-04-15

1. Stanford HAI released the AI Index 2026, which documented major performance gains in AI models, a narrowing gap between the US and China, mounting safety concerns and declining public trust, and highlighted hardware supply‑chain concentration around a single foundry (TSMC).

2. Anthropic's Claude Mythos was shown in UK tests to be capable of autonomously completing a full simulated attack on a weakly defended enterprise network, and Anthropic subsequently restricted access while European authorities reported limited visibility into the system.

3. MIT Technology Review published a report on agentic AI adoption in software engineering that found 51% of teams were using agents in a limited way, 45% planned to adopt within 12 months, respondents expected delivery speed to accelerate (98% expected gains averaging 37%), and organizations cited compute costs and integration as primary barriers.
